In the context of the Berlin Conference of 1885, the agreement finally reached by Germany and France to establish the boundaries of the countries’ respective colonies at the River Campo of the Muni region ignored Spanish sovereignty over the region. This led to numerous incidents between France and Spain, even after both «friendly nations» signed a permanent status quo to establish their frontiers. The intervention of certain governors under the instructions of the executive committee of the Sociedad Española de Africanistas y Colonistas managed to prevent the French from expelling the Spanish from the continent. The purpose of this article is to draw attention to the decisive roles played by governors Jose de Barrasa and Fernandez de Castro in this embroiled chapter of history.
